Darwin Streaming Server

Hey I have Darwin Streaming Server installed on a remote Fedora Core Server and all is working well (server is properly configured and running, sample files is streaming). Server is streaming from port 80 I need some basic advice on which software to use to be able to broadcast live from a windows machine. Also how to do the following: 1) Connect to my Linux server and broadcast from any XP / Vista machine. 2) Allow internet users to connect and view the stream (best clients etc) 3) Allow users to view stream directly from a web browser. Many Thanks Phil
